For quite a while I had ESLint rule `@typescript-eslint/no-unused-vars` disabled cause (I thought) it duplicates TypeScript rules noUnusedLocals and noUnusedParams. Few experiments confirmed that belief. Today I reenabled that ESLint rule on quite a big codebase and, to my surprise ... discovered that `noUnusedLocals` does miss some unused vars! I didn't notice a *pattern of missing* yet (TS bugs?) but the point is that EsLint may find "unused-var" bugs that TS doesn't. Both TS rules are disabled in Deno b.t.w and they recommend to use Linter instead. So I decided to follow the same path and recommend it to you. - Disable `noUnusedLocals` and `noUnusedParams` to have more flexibility while development (it really helps). - Enable `@typescript-eslint/no-unused-vars` to catch "unused-something" places The latter will need an extra config like: ``` "@typescript-eslint/no-unused-params": ["error", {"argsIgnorePattern": "^_", "varsIgnorePattern": "^_"} ], ```
